Is An Post aware of the importance of these envelopes and what they contain? Are protocols in place with An Post concerning what happens to undelivered letters? Moving to those certificates that bounce back via email, then, will those certificates now be posted out to the people concerned? I ask those questions because this is a critical piece of State documentation that gives people liberties and freedoms and access to indoor dining, etc. I am interested in knowing, therefore, what procedures are in place to deal with issued certificates that are not successfully delivered by email or post.
